Description

Wire Processing Equipment {APPARATUS FOR PROCESSING WIRE}

The present invention relates to a wire processing apparatus, and more particularly, to a wire processing apparatus that can press the wire supplied from the wire cutting portion by the docking means to be accurately seated on the emvil of the attachment.

In general, a wire processing apparatus is a device for removing the coating at the front end or the rear end of the wire, mounting the electrode terminal at the front end or the rear end of the wire from which the coating has been removed, and cutting the wire provided with the electrode terminal to a predetermined length.

Such a wire processing apparatus is comprised of the wire cutting part which removes the coating | cover of a wire, and cut | disconnects, and the attachment which attaches an electrode terminal to the edge part of the wire supplied from the said wire cutting part.

The said wire cutting part performs transfer of a wire, cutting of a wire, removal of a wire coating material, and discharge of a wire.

That is, the wire cutting unit removes the coating from the transfer unit for transferring the conductive wire, the direction change unit for switching the traveling direction of the wire transferred from the transfer unit to guide the attachment, and the end of the wire transferred by the direction change unit. It consists of a stripping mechanism for cutting.

In the wire cutting part having such a structure, when the wire is transferred to the turning part by the conveying part, the turning part supplies the wire to the stripping mechanism. Then, when the wire reaches the stripping mechanism, it is cut by the thickness of the coating of the wire by a pair of cutter blades arranged up and down.

In a state where a pair of cutter blades are infiltrated into the sheath of the wire, the turning part reversely rotates so that the sheath can be reversed and the sheath can be removed.

As such, when the coating of the wire is removed, the wire may be supplied to the attachment by rotating the redirection unit in the attachment direction.

The attachment may include a ram portion capable of vertically reciprocating movement, an emvil disposed under the ram portion, and a wire and a strip electrode terminal provided from the wire cutting portion to be seated, and the strip electrode terminal being moved up and down by the ram portion. It is composed of a conveying unit for moving a predetermined pitch, and a cam unit provided on one side of the ram unit by moving the conveying unit and the ram unit by a cam movement to move the conveying unit forward or backward in the emville direction in accordance with the raising and lowering movement of the ram unit.

An attachment having such a structure is, when the electrode terminal is pitched forward by the transfer unit and is seated on the upper part of the emvil, when the wire is supplied from the wire cutting part and seated on the electrode terminal of the emville, the ram part descends so that the electrode The terminal may be pressed and pressed against the end of the wire.

As such, when the electrode terminal is coupled to the wire by an attachment, the direction changer rotates back to its original position so that the tip of the wire is aligned in the direction of the stripping mechanism.

In this state, the stripping mechanism is actuated and the wire is cut to a certain length and then discharged.

Such a wire processing apparatus is adapted to rotate the turning part in a state where the wire is fixed so that the tip of the wire approaches the embil of the attachment disposed on the same line from the side direction. May interfere.

Therefore, in order to prevent interference between the wire and the electrode terminal, by disposing the direction changer disposed on the same line as the emvil higher than the position of the emvil, the tip of the wire fixed to the direction change unit even if the direction change unit rotates in the emvil direction. Since it rotates at a position higher than the emvil, the tip of the wire can be prevented from interfering with the electrode terminal on the emvil.

However, in the conventional wire processing apparatus, since the end of the wire is disposed higher than the position of the electrode terminal on the emvil, the ram portion falls from the top in a state where the end of the wire is aligned with the upper end of the electrode terminal, and thus the wire is connected to the electrode terminal. When pressed inward, since the end of the wire is in the free end state, the end is sagging downwards, and thus the wire is generated from side to side in the process of being inserted into the electrode terminal.

Accordingly, the present invention has been made to solve such a problem, an object of the present invention is to provide a wire processing apparatus that can be pressed to the correct position and coupled with the electrode terminal when the end of the wire is pressed by the ram portion. .

In the state where the pair of cutter blades 36 and 37 invade the sheath of the wire W, the guide rollers of the guide part 30 reversely rotate so that the sheath W can be reversed to remove the sheath. have.

As such, when the covering of the wire W is removed, the body 48 is rotated laterally along the first arrow direction a1 (Fig. 3) to rotate in the lateral direction of the attachment 5 so that the wire W It may be supplied to the attachment 5 through the wire guide 26 to be described later.

In addition, the wire W supplied to the attachment 5 may have an electrode terminal T pressed at the front end thereof by the ram unit 15.

This attachment 5 comprises an attachment 5 of a conventional structure. That is, the attachment 5 includes a ram unit 15 capable of vertically reciprocating movement; An emvil 11 disposed under the ram 15 to seat the wire W and the band-shaped electrode terminal T supplied from the wire cutting unit 2; A transfer unit 10 for moving the belt-shaped electrode terminal T to the emvil 11 by a predetermined pitch when the ram unit 15 moves up and down; It is provided on one side of the ram unit 15 by moving the transfer unit 10 and the ram unit 15 by the cam motion to move the transfer unit 10 in the direction of the embil (11) in accordance with the lifting and lowering movement of the ram unit 15. Or a cam portion 19 for reversing.

In the attachment having such a structure, the strip-shaped electrode terminal T is conveyed by a predetermined pitch in the direction of the emvil 11 by a conventional attachment driving method.

That is, when the ram part 15 moves up and down, the cam surface 17 also moves up and down, and the cam roller 19 which contacts the cam surface 17 in rolling contact rotates clockwise and counterclockwise.

By the rotation of the cam roller 19, the pusher 21 pushes the belt-shaped electrode terminal C disposed on the upper portion of the feed table 10 in the direction of emvil 11.

Through this process, the electrode terminal T is seated on the upper part of the emvil 11 by advancing a predetermined pitch in the direction of the emvil 11 by the transfer unit 10.

In this state, when the front end of the wire W supplied from the wire cutting unit 2 reaches the upper portion of the emvil 11, the ram unit 15 moves in the second arrow direction a2 (Fig. 3). By falling along the electrode terminal (T) can be pressed to the front end of the wire (W).

In this case, the docking means 7 is provided so that the tip of the wire W may be disposed at an accurate position inside the electrode terminal T.

The docking means (7) is mounted on one side of the ram portion 15 and the pressing portion 24 for vertically reciprocating movement like the ram portion 15; It is hingedly connected to the lower end of the pressing portion 24, the lower end line is located below the lower end line of the ram portion 15, so that when the lowering the wire guide portion 26 before the ram portion 15 A punch 29 for pressing; It is disposed on one side of the direction changing section 32 to guide the wire (W) to the upper part of the emvil 11 of the attachment (5), by pressing the punch 29 to the wire (W) to the electrode A wire guide portion 26 leading to an upper portion of the terminal T; And an elastic member 42 elastically disposed below the wire guide part 26 to absorb an impact in the vertical direction when the punch 29 strikes the wire guide part 26.

In the docking means having such a structure, the pressing portion 24 is composed of a housing 25 connected to one side of the ram portion 15, and a pressing shaft 27 protruding from the lower portion of the housing 25.

In more detail, the housing 25 is integrally connected to one side of the ram 15 by a bolt. Therefore, the housing 25 can be separated from the ram portion 15 by releasing the bolt as needed during maintenance or replacement.

Of course, the connection method of the housing 25 is not limited to the bolt, but a method such as welding is also possible.

The pressing shaft 27 protrudes downward from the lower portion of the housing 25, and the punch 29 is connected to the lower end thereof.

Therefore, when the ram part 15 reciprocates up and down, the pressing shaft 27 and the punch 29 move up and down.

The punch 29 is connected by the pressing shaft 27 and the hinge pin h, so that when the pressing shaft 27 is lowered, the bottom surface of the punch 29 is the upper surface of the wire guide portion 26. The wire guide portion 26 is pressed downward by contacting the.

At this time, the lower end line of the punch 29 is located lower than the clamper 23 of the ram portion 15. Therefore, when the ram portion 15 is lowered, the punch 29 is also lowered, and the wire W is guided inside the electrode terminal T by first contacting the upper surface of the wire guide portion 26. .

In addition, when the end of the wire W is seated inside the electrode terminal T, the crimp 23 of the ram unit 15 compresses the electrode terminal T so that the electrode terminal T is connected to the wire. It can be coupled to the correct position at the tip of (W).

The wire guide portion 26 is disposed between the upper and lower plates 46 and 44 disposed in a horizontal direction on one side of the body 48, and the wire W is disposed between the upper and lower plates 46 and 44. It includes a wire guide pipe 45 penetrates.

A predetermined space is formed between the upper and lower plates 46 and 44, and the wire guide pipe 45 is disposed in the space.

In addition, the elastic member 42 is disposed below the lower plate 44. That is, the elastic member 42 is elastically disposed under the lower plate 44 to absorb the impact of the wire guide 26.

That is, the elastic member 42 preferably includes a compression spring, an upper portion of which supports the bottom of the lower plate 44, and a lower portion of which is supported on the upper surface of the pedestal 40 of the body 48.

Therefore, when the wire guide portion 26 is pressed downward by the punch 29, the elastic member 42 can be buffered by absorbing the impact of the wire guide portion 26.

In addition, one end of the wire guide tube 45 communicates with a through hole 52 formed in the wall 50 of the body 48. Therefore, the wire W supplied from the turning part 32 is inserted into the wire guide tube 45 through the through hole 52 of the wall 50.

The wire W inserted into the wire guide pipe 45 is discharged to the outside through the other end of the wire guide pipe 45.

At this time, the body 48 of the wire cutting portion 2 is rotated in the attachment direction by the motor (M).

Therefore, the wire W discharged to the outside through the wire guide pipe 45 approaches in the lateral direction of the emvil 11 of the attachment along the first arrow direction a1 (Fig. 3).

The tip of the wire W is positioned above the emvil 11 of the attachment.

In this state, when the punch 29 presses the upper portion of the upper plate 46, the upper and lower plates 46 and 44 are lowered, and the wire guide tube 45 also supports the wire W. Descend from.

As a result, the wire (W) is lowered by the punch 29 in a state supported by the wire guide tube 45, so the clamper 23 of the ram portion 15 directly presses the tip of the wire (W) and lowers it. It is possible to prevent the flow of the front end of the wire (W) than to make.

The punch 29 is integrally connected to the pressing shaft 27 by a hinge pin h, so that when the punch 29 contacts the upper plate 46 of the wire guide 26, the punch 29 ) Will be bent at an angle.

At this time, the angle of the punch 29 can be folded at various angles, but preferably can be folded within the range of 5 degrees with respect to the pressing shaft (27).

As described above, when the punch 29 is in contact with the wire guide portion 26, the punch 29 may be bent with respect to the pressing shaft 27 to absorb a portion of the impact of the punch 29.

As described above, when the ram portion 15 descends while the end portion of the wire W is aligned with the upper right position of the electrode terminal T, the punch 29 first of the wire guide portion 26. By contacting the upper plate 46 and pressing the wire guide portion 26 downward, the wire W reaches the inside of the electrode terminal T in a state of being fixed by the wire guide portion 26.

In this state, the electrode terminal T is pressed by the crimper 23 of the lowered ram part 15 so that the electrode terminal T can be coupled to the end of the wire W at the correct position.

Hereinafter, the process of coupling the electrode terminal to the end of the wire by the wire processing apparatus according to an embodiment of the present invention will be described in more detail by the accompanying drawings.

1 to 3, when the electrode terminal (T) is coupled to the end of the wire (W) by the wire processing apparatus 1 proposed by the present invention, first the wire (W) to the wire cutting portion ( It guides into the guide part 30 of 2).

The wire W drawn into the guide part 30 is supplied to the direction changing part 32 by being guided by a plurality of guide rollers R.

At this time, the direction change unit 32 is aligned in the direction of the stripping mechanism 33. Therefore, the wire W supplied to the turning part 32 is transferred by the pair of rollers R1 and is supplied between the upper blade 36 and the lower blade 37 of the stripping mechanism 33.

In this state, the upper blade 36 and the lower blade 37 move up and down to invade the coating of the wire W to form scratches on the coating.

With the upper blade 36 and the lower blade 37 invading the covering, the pair of rollers R1 are rotated in reverse to reverse the wire W in the direction of the turning section 32 to cover the coating. Can be removed from W).

After removing the coating of the wire W in this manner, the body 48 of the wire cutting portion 2 is rotated by the motor M in the attachment direction.

Then, the pair of rollers (R1) of the direction changing section 32 is driven to discharge the wire (W) in the direction of the attachment (5) through the wire guide pipe (45).

At this time, the wire (W) discharged to the outside through the wire guide pipe 45 approaches in the lateral direction of the emvil 11 of the attachment along the first arrow direction a1 (Fig. 3).

In addition, since the redirection unit 32 is disposed at a position higher than the emvil 11, the wire W may change direction to approach the lateral direction of the emvil 11, but the wire W may be moved to the emvil 11. 11) can be prevented from interfering.

As such, when the end portion of the wire W reaches the upper portion of the emvil 11, the ram part 15 descends. When the ram unit 15 is lowered, the housing 25 and the pressing shaft 27 provided on one side of the ram unit 15 are also lowered, and the punch 29 connected to the pressing shaft 27 is also lowered.

At this time, since the lower end line L1 of the punch 29 is located below the crimper 23 of the ram part 15, the punch (before the crimp 23 is crimped to the electrode terminal T). The bottom of 29 contacts the top of the wire guide 26 first.

When the ram portion 15 is continuously lowered while the punch 29 is in contact with the wire guide 26, the punch 29 presses the upper plate 46 of the wire guide 26 downward. Done. In this process, since the punch 29 is hingedly connected to the pressing shaft 27, the punch 29 is bent at an appropriate angle.

Therefore, the punch 29 can be prevented from primarily pressing the upper plate 46 of the wire guide portion 26 by absorbing excessive shock.

In this way, the punch 29 presses the wire guide portion 26 downward, until the end of the wire W is seated inside the electrode terminal T disposed on the emvil 11.

When the end of the wire (W) is seated on the electrode terminal (T), the clamper 23 of the ram portion 15, which is also lowered to press the electrode terminal (T).

The crimper 23 presses the electrode terminal T to wrap the wire W seated inside the electrode terminal T, and the electrode terminal T may be coupled to the end of the wire W.

At this time, the shock transmitted to the wire guide portion 26 may be absorbed by the elastic member 42 to be buffered secondarily.

As described above, the end of the wire (W) can be pressed by the docking means (7) can be seated in the correct position of the electrode terminal (T).
